Docker CMO, Tim Anglade:
For those of you catching up, we recently emailed accounts that are members of Free Team organizations, to let them know that they will lose features unless they move to one of our supported free or paid offerings. This impacted less than 2% of our users…
The Docker Free Team subscription was deprecated in part because it was poorly targeted. In particular, it didn’t serve the open source audience as well as our recently updated Docker-Sponsored Open Source program, the latter offering benefits that exceed those of the deprecated Free Team plan.
We’d also like to clarify that public images will only be removed from Docker Hub if their maintainer decides to delete them. We’re sorry that our initial communications failed to make this clear.
Just to be clear: their apology is not about the change, it’s about how they communicated the change. There’s more details in the post about deleting public images, squatting names, etc, but that’s the gist.
